Why Wi Fi does not work on the Samsung phone. Wi fi is connected but not loading. The "Android" does not turn on Wi-Fi: possible failures and methods to eliminate them. Wi-Fi does not work: setting date and time

Wi-Fi is a technology that allows electronic devices to transfer data or connect to the Internet via the wireless network. Nowadays, the use of Wi-Fi becomes very common, and we can see how this technology is used by a wide range of devices, such as smartphones, tablets, gaming consoles, smart TVs, etc.

However, this technology has a number of restrictions. First, it is not as safe as a wired connection, but it is solved by using the encryption of protected access (WPA2), which allows preventing unauthorized access to the network. If you do not have sufficient knowledge to customize your home or office network, it is better to trust this business professionals. It is enough just to fill out the form on http://kompom.kiev.ua/ and the setting will be made quickly and efficiently.

Another problem: Wi-Fi disappears periodically. Usually, in the absence of activity, the phone or tablet loses with the WiFi router and does not see the network before restarting Wi-Fi on a mobile device. The reasons for which the connection to Wi-Fi is lost can be somewhat, in this article we will look at several options for solving the problem when android loses the Wi Fi network.

If you encountered the problem of disconnecting Wi-Fi on the Android device, try the following options for settings and you can connect a device over a wireless network without much trouble.

Wi-Fi overflow network

The biggest interference for Wi-Fi signal create adjacent wireless networks. The problem is that most Wi-Fi devices work in the already busy range of 2.4 GHz, and the high density of the signals may interfere with each other reducing the speed and performance of networks.

Decision: Use a two-band router that can operate both at a frequency of 2.4 GHz and 5 GHz at the same time. The frequency band of 2.4 GHz will be maintained by most devices, but it has only three non-recipient channels. On the other hand, 5 GHz has 23 non-varying channels, increasing the probability of no interference in this range. If your router can operate in the 5 GHz band, use it to solve the problem of overflowing Wi-Fi network.

Configure Wi-Fi Channel

2.4 GHz Wi-Fi band has 11 channels and each of them is separated from each other by a 5 MHz band and has a width of 20 to 22 MHz. This means that each channel will overlap neighboring channels for 10 MHz and this is called as overlapping channels.

Decision: In the case of the use of channels 1, 6 and 11, overlap, which creates interference, will not be, as it is not overlapping channels. To work on these channels, users will need to enter the router settings and find the setting called "Channel" or "Wireless Channel". From the drop-down menu, you need to select the desired channel number.

Most manufacturers resort to different methods to increase battery life. Android users of smartphones are forced to include such power saving functions in their devices. One of these features is to disable Wi-Fi when the phone is inactive or when the device has a low battery charge. Such features of Wi-Fi in sleep mode create problems when connected to the network as needed.

Decision: Just configure the parameters of your Android device and make sure that you always have Wi-Fi enabled, even when the device is not used. To do it on devices running on Android 2.3 Gingerbread and above, you need to do the following. Go to the Settings menu - Wireless networks - Wi-Fi and choose additionally - Wi-Fi in sleep mode Do not select "Do not turn off".

On those devices that work on Android 4.0 ICS and above, go to the Settings menu - Wi-Fi, select Advanced and install the Wi-Fi option during sleep - "always."

Change DNS servers

Changing the DNS servers can solve the Wi-Fi problem when the Internet network disappears on the phone. Go to Settings section - Wi-Fi and turn on Wi-Fi. If this is a well-known network, you will have to "forget" it, and then connect again. When you see the password input window, click on Extra options And select "Static" from IP settings in the drop-down menu. Then scroll down and enter the IP address of the DNS server you would like to use in DNS1 and DNS2 field. Now enter Wi-Fi password and connect the network.

Reset to factory settings

If none of these methods helps, perform hardware reset of your Android device. If after that you have problems when connecting to Wi-Fi is lost, it may be a hardware problem. You may have to be attributed to the device to the service center to correct the problem.

We looked at the most common causes of Wi-Fi disabling, which occur in Android devices. We hope this will help in solving the problem and will allow you to configure a steady Wi-Fi connection. Also, pay attention to specialized applications, because there are many applications in the Google Play store, the use of which will help ensure a confident connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.

⭐️⭐️⭐️⭐️⭐️ In this article, I will scatter the situation when there is no Internet on Android via Wiifi. Those. There is a network connection itself, the Waifa icon is active, but it is impossible to enter the Internet and messengers (Telegrams, Vibers, Skype) and other applications (Instagram, VKontakte, etc.) are not connected.

In most cases, it helps the reboot of a smartphone or a router, which distributes the wireless network. Another reason can be a software error in the work of the Android and the wrong adjustment of the router.

This article is suitable for all brands producing phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, Zte, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

I note! If you use the WiFi public network or private corporate, then the likelihood of the blocking of some social networks and messengers is great. This is often practiced and have to come to terms with the situation.

Checking internet access

Before in the work of a smartphone or a router, make sure that the Internet is all right. What can be wrong with him:

You did not pay, so the provider has suspended Internet access. Make sure that the wire has access to the network.
In the router settings, there are restrictions on visiting individual sites or limit on traffic (normal practice for open networks in public places).
There were problems on the provider side.

After the exclusion of these factors, proceed to the diagnosis that allows you to understand what device is hidden by the cause of the problem.

The easiest way is to connect to the wireless network from another phone / tablet / laptop. If another device goes into the network, then problems in the phone that cannot establish a correct connection.

Failures in Android

Restart your mobile device. If the cause of the problem was a minor system failure, the restart of the system will eliminate it.

After re-start when saving an error, forget the network and then re-connect to it.

Network Forgetting and Re-connection helps to eliminate the inconsistency of Wi-Fi parameters on the phone and router.

If the network deletes does not help, check the status of the proxy server on Android. It must be turned off:

Go to the "Wi-Fi" section of the settings and select a network for connecting.
Mark the "Advanced" item ("Extended Settings").
Make sure that there is no "Proxy server" field.

Increase

Another reason that the phone does not enter the Internet may be the wrong date. To check it and change it:

Open settings.
Select the section "Date and Time".
Set the time and date manually or tick the "Date and Time of Network" and "Network Time Zone".

Increase

After setting the correct dates, connect to Wi-Fi. If the wireless network really works, you can enter the Internet.

Check and configure the router

If, as a result of a kind of diagnostics, you found out that they occur on all devices that are connected to one wireless network, then look for the cause of the error in the router settings.

Completely common situation: the user tries to connect to Wi-Fi from his phone, but nothing happens. After reading the information below, you will learn why this happens and how to solve the problem.

Initial phone check

Manufacturers are actively working on improving the stability of mobile operating systems, but periodically any program gives a failure. That is why the solution to the problem is recommended to start with the inspection of the operability of the phone. For Android, iOS and Windows Phone (Windows Mobile) recommendations in this case are identical. Stick the following sequence.

1. Restart the device and try to connect to Wi-Fi again.

2. Evaluate the number of connection signal indicators. If there are less than 3, try moving closer closer to the router or other used wireless Internet source to improve the quality of the connection.

3. Make sure the charge saving mode is disabled. If necessary, connect the network adapter.

4. Disconnect Bluetooth. Wireless connections can operate in the same range, which is why interference is created.

5. Disconnect the "aircraft" mode, if active.

6. Try to activate access to your location information and connect to Wi-Fi - the legislation of some countries blocks a connection through wireless networks with an inactive state of said option.

If earlier WiFi connection worked

If in the past you successfully used the current network now, delete this connection from your phone's memory. To do this, go to the network list, click on a problem connection for a few seconds (before the context menu appears) and delete the connection.

If nothing happened, try connecting from the phone to any other available connection. In this case, only employees of the service center will help with a large proportion of probability in this case with a large share of the probability - only employees of the service center will help to correct the situation.

Make sure if the connection works. To do this, try to connect to it using any other device that features Wi-Fi function. If the connection does not work, make changes to the router settings.

Important note! The order of login in the router settings is changing depending on the manufacturer and model of equipment. In most cases, to gain access, you need to enter the address 192.168.0.0 or 192.168.0.1 in the address bar of the browser. Standard login and password - admin. If it does not work, specify the relevant information for your router in the manufacturer's instructions.

Previously try simply restart the router - quite often they "hang", because of which access to the Internet is blocked.

Further procedure is as follows.

First, you must make sure that the security key entered. Try entering the password to connect to the selected access point again, but more attentive, with the "Display Symbols" option activated (Show Password).

If you do not remember the password, specify it in the router settings.

For example, the order of interaction with the D-Link router is shown. In your case, everything will be almost the same, minor changes can affect only the interface, the names of the menu items and other little things.

After hitting the router settings page, do the following:
Click the "Advanced Settings" button;
In the Wi-Fi window, open the Safety Settings link;
In the PSK Encryption key line, see the password and make sure that it is this combination that you enter when trying to connect to Wi-Fi from the phone.

Secondly, make sure that the router settings are correct - you need to check whether the DHCP technology is enabled. When it is turned off, the phone cannot receive an IP address, because of which the connection will not work.

On the Router Settings page, click "Advanced Settings" and find the LAN category in the Network window.

Activate DHCP if the function is disabled by moving the "Mode" string to the "Allow" state.

Save the changes, restart the router and try to connect to Wi-Fi from the phone.

If this does not help, there are 3 options:
call the provider support and find out if the Internet works at all and have not made any changes to the connection settings;
pass the phone into repair;
Pass to repair / replace the Internet router.

Therefore, we will look at what to do when problems arise with the Wi-Fi connection on your Android device. Today we will find the answer to the question why Wi-Fi does not turn on on android?

Causes and decision

Wai Fi on the phone or Android tablet may not work for several reasons. It should be noted that not only the owners of tablet computers may encounter, but also people using mobile phones on the basis of this popular system. How to be users if the WiFi SAMSUNG device does not turn on, we will look for the cause and eliminate the root of the problems.

One of the root causes, if Wi-Fi stopped working on Android, which is extremely rare - this is incorrectly established date and time. To eliminate it, it is enough to go to the "settings", set the correct date and time, given the time zone.
The second and most frequent problem is a password change when automatically connected to the network. That is, the password is changed by the user, but the Android system still "does not know." To eliminate this problem using the interface or hotkeys, go to the Wi-Fi network connection settings, delete the profile with which it was configured to connect and create a re-selection connection, select your own connections available, enter the necessary characters, in the window that appears. Next, the connection to the passrollated network will occur automatically.
Failures in software (software) - the third of the possible reasons when Wi-Fi on Android ceases to connect. To do this, use the Wi-Fi Fixer utility, created specifically to solve this problem.

We go to the "Settings" select "Restore and Reset", click "Reset Settings". Either make a full "Hard Reset", but then all data is deleted, that is, the device will be, as after purchase.

Sometimes users set the unsuitable Android firmware, as a result of which the correct operation of the radio modulus is disturbed, including the WiFi module on samsung phones or tablets. The output in this situation is to install or update the basic firmware on Samsung.

Again these viruses!

One of the most unpleasant reasons when the Wi Fi does not turn on is the impact of malicious programs, the so-called viral programs, to the operation of the device's radio modules. To eliminate viruses in the phone, you need to make a deep scanning of the built-in antivirus.

Customize router

The revered seventh place occupies an error when connecting to Wi-Fi - failure or incorrect adjustment of the router. Eliminating this error is carried out in the settings of the router. How to do this can be learn from the instructions of the device. This is especially true if the home network is used. In the control menu, select "Wireless Settings". We change the parameter to "Auto", in the "Channel" line, and the "Mode" string to the "11 BGN mixed" parameter. Turn off the filtering of the addresses to ensure that the router does not filter addresses connected devices. We try to connect.

And now it's right to the master

If none of the above methods helped, then the problem in the radio modulus itself, WiFi will not work until they disappear into the microcircuit. In this situation, the best solution will be the appeal under warranty in the service center (for example, Samsumg) or to a competent and proven computer master.

It must be remembered, any interference of non-competent persons in the system's work, even when solving a problem when Wi Fi does not connect, it creates a huge risk, turn your favorite gadget to a useless piece of plastic, to resuscitate significant financial costs and your nerves.
